Question

I have these two variables being set in the controller. How do I cache these so they don’t communicate with the database each time, only the first time.

@tablenutrients = Nutrient.find(:all)
@columnnutrients = @tablenutrients.collect {|x| x.nutrient}

Answer 1

what @djlumley said.

In general, you can also configure and use ActiveSupport::Cache::Store to explicitly store your own custom variables. You could then get/set cached values, for example, like this:

@tablenutrients = Rails.cache.fetch("tablenutrients") do 
  Nutrient.find(:all)
end
